To all whom it may concern:

Be it known that I, WILLIS G. SHocKEY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Massage-Machines, ofwhich the following is a specification.

The apparatus of the present invention is designed for performing thework usually attributed to such machines, and more espe cially for thepurpose of massaging cream and other facial applications into-the skin;and has for its object to produce a device which will be cheap andsimple of construction; and which will be operated entirely by springpower, thus dispensing with the electrical connections or othercomplicated actuating devices usually employed with such articles. Themechanism is of such a nature that it may be inclosed within a casing ofsubstantially small size and-easily carried from place to place, and theweight of the mechanism will be such that no inconvenience will beexperienced in holding the apparatus during the massaging operation orin carrying it in a satchel or other receptacle when desired.

The apparatus of the present invention receives its vibratory motionthrough the contact of companion, oppositely extending arms attached tothe massage instrument, with the serrated surface of a member which isactuated by means of a spring niotor acting in conjunction with asuitable train of gearing; and the massage instrument itself is of aresilient nature, so that the vibratory motion imparted thereto will beaug mented through the flexibility of the acting end of the massageinstrument.

In the drawings, Figure 1 is a side elevation of the completed device;Fig. 2 is a vertical section therethrough; Fig. 3 is a section on line33 of Fig. 2; and Fig. 4 is a detail of the massage instrument and theoppositely extending arms thereof.

The device is inclosed within a casing 5, which is formed of companionsections of sheet metal of any suitable composition, each of which is inthe form of a shallow cylindrical box, open at one end, the free ends ofthe sections adjoining at approxi mately the center of the device; andthe sections are held together by means of suitable fasteners 6. Lyingwithin the sections 5 are companion partition walls 7 and 8, each ofwhich is secured to the respective section in which it lies, and each ofwhich is held against movement within the sections through the medium ofthe fastening means 6. The partitions and sections cooperate to producean inner chamber 9 and an outer chamber 10. It will, of course, beunderstood that the terms inner and outer as used are merely for thepurpose of facilitating the description and are not necessarily alimitation on the construction. The inner chamber 9 serves as a housingfor a ribbon spring 11, which is secured at one end 12 to one of thefastening members 6, and is attached at its other end 13 to a shaft 14,and the shaft extends outside of the casing and has aflixed upon itsouter end a suitable grip or handle 15. As shown in Fig. 2, the shaft 14is surrounded by a suitable metallic bushing 16, and the handle 15 isrigidly attached to this bushing, the connection between the handle andthe shaft being efiected through the medium of a screwthreaded stem 17,which is provided with a suitable finger piece 18 upon the outer endthereof. This provides a connection whereby, when the stem 17 is fullyinserted, as shown in Fig. 2, rotation of the handle 15 will impartrotation to the shaft 14, and thus wind up the spring 11; but when thestem 17 is withdrawn, so that its inner end lies free of the bushing 16,the shaft can then revolve independently of the handle and bushing; and,as the shaft rotates, by reason of the tension of the spring 11, thehandle 15, which is grasped by the operator, will remain stationary,thus providing a suitable grip for the operator during the massagingoperation.

Fixedly secured to the shaft 14 is a ratchet wheel 19, which isconnected to a gear wheel 20 through the medium of a dog 21, and thegear wheel 20 meshes with a pinion 22 which is mounted upon a stub shaft23. The pinion 22 is secured to a gear wheel 24, which meshes with apinion 25 looselymounted upon the shaft 14 and fixedly secured to a disk26, which has its edge formed with a plurality of teeth 27, producing aserration around the periphery thereof.

Pivotally mounted in the partition 8 and in the outer wall of one of thesections 5 is a stem 28, out from which project oppositely extendingarms 29, each of which is provided at its end with a roller 30, theserollers being so positioned, as shown in Fig. 3, that when one is lyingintermediate two of the teeth 27 the other is lying on top of one of theteeth, so that a constant rocking motion is imparted to the stem 28 asthe disk 26 is revolved, such rocking motion being due to the alternaterising and falling of the ends of the arms 30, and as one of the ends isrising while the other is falling they Will never be acting inopposition to one another to minimize the effect of the rocking motionupon the stem.

As shown in Fig. 2, the gearing, serrated edge disk, and arms are alllocated within the chamber 10, and the stem 28 terminates in a massagemember 31, which in the form shown comprises a cup-shaped receptacleformed of coil spring wire. instrument possesses in itself considerableresiliency and vibratory power, and hence, when the rocking motion ofthe stem 28 is imparted to this member, it will set it in vibration, andthe ordinary vibration created therein will be augmented through thevibration of the spring metal of which it is composed, and thus a greatefficiency of vibration will be obtained in the acting end of theinstrument.

The movements of the disk 26 may be controlled through the manipulationof a finger piece 32, which may be of any usual and well known formationand serves to withdraw a locking pin 33 from engaging position betweenthe teeth of the disk 26.

The operation will be understood from the foregoing, but briefly is asfollows: The screw 17 is first turned into the position shown in Fig. 2,and the operator turns the handle 15, Winding up the spring 11. Afterthe spring has been wound to the desired point, the screw 18 iswithdrawn to permit of the rotation of the shaft 14 independent of thehandle, and the finger piece is actuated to permit the disk'26 to berotated through the expansion of the spring acting and driving the gearconnection between the shaft 14: and the disk 26. As the disk isrotated, the serrated edge thereof will pass by the ends of the arms 29and impart a vibratory motion to the stem 28, which in turn will vibratethe massage member 31. The instrument can be stopped at any time desiredby merely releasing the finger piece 32.

I claim:
